Watch 'Extremely scary ghost elevator prank in Brazil'

This terrifying TV prank was conceived by the Brazilian Silvio Santos Program. Alone in a dark lift with no power is unsettling experience for anyone. But things get creepier: a ghost girl appears from nowhere, frightening the elevator riders.

ABC News reports that the Brazilian variety show Programa Silvio Santos, aired this pegadinha ("prank") on Sunday. The video posted to YouTube has gone viral with over 3.5 million views on YouTube alone.

The video shows a woman in an empty lift. The power goes off. She waits uncertainly in the dark for a while. When the lights come on, she sees a creepy "ghost apparition" in the lift–a pale faced, tousle-haired girls stands, carrying a doll. She looks like a ghost child from a horror movie scene ("The Ring").

Unknown to the victims, the "ghost" entered the lift from a trap door at the side when the power went off.

Watch a woman stand, literally petri-fied. She dares not look!

Things get creepier when the pranksters, taking sadistic delight in torturing their victims, switch the lights on and off. The girl appears and disappears, screaming when she appears.

Some of the victims scream in terror. Two women hold each other and cower in a corner. A man tries to blot out unreality by covering his face with his palms. He runs out of the lift as the door opens. The ghost girl chases after him.

But did the pranksters consider the risk that some plucky victim, feeling trapped in the enclosed space, could launch an attack on the "ghost" with lethal force?
